NITED STATES PATENT GEORGE W. GATES, OF GRAND RAPIDS, MICHIGAN, ASSIGNOR TD CHARLES l3. JUDD, OF SAME PLACE.

CARPET-SWEEPER.

SPECIFICATION forming part of Letters Patent No. 284,833, dated September 11, 1883 Application filed July 27, 1882.

To all whom it may concern.-

Be it known that I, GEORGE W. GATES, of the city of Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Carpet-Sweepers, of which the following is a specification.

My invention relates to improvements in carpet-sweepers; and the objects of my invention are as follows: To increase the efficiency of a carpet-sweeper by improving the means by which the vertical adjustment of the brushroller simultaneously at each end is obtained; the means of adjusting the brush-roller by the movement of the handle of the sweeper, and to form a cheaper, simpler, and more durable device for dumping the dust from the sweeper. I attain these objects by means of the mechan ism illustrated in the accompanying drawings, in which Figure 1 is a plan View of that end of the sweeper in which the driving wheels are placed. Fig. 2 is a plan View of the other end of the sweeper, and Fig. 8 is a perspective view of a bearing-block which forms a bearing for one end of the brush-roller.

Similar letters refer to similar parts throughout the several views.

H represents the bail, attached to the plates A and A, one on either end of the sweepercase. The plates A and A are each provided with a slot. (Shown byS and S in the drawings.) In the end of the sweeper-case bearing the driving wheels is a vertical slot, through which the journal of the brush-roller projects into the slot in plate A, as shown in Fig. 1. Into the other end of the sweepercase is fitted the bearing-block E,which block is provided with a groove, 0, and ear E,which ear forms the bearing for the end of the brushroller. On block F is pin P, which projects through a vertical slot in the end of the sweep er-case and into the slot S in plate A. The object of using'block F is to allow the easy removal of the brush-roller. The plates A and (MorleL) as well as the increased friction, is regulated by the operator from the handle of the sweeper, the fulcrum being placed above the bearings of the brush-roller. D D represents the door which covers the dust-opening. It may be a simple piece of metal, or any other suitable material, attached to the sweeper-case by the staples or hinges n n, and so constructed as to open or shut freely. The plate A may be made to project, as shown by X, so that it will slide or pass over the door D and hold it securely in position at all times, except when the handle is in a perpendicular position.

Having thus described my invention, what I claim to have invented, and desire to secure by Letters Patent, is-

1. In a carpet-sweeper, the plate A, provided with the slot S, in combination with the bail H, block F, bearing 1, and the brushroller, substantially as described. 2. The combination of the plate A, having the slot S, and a projection, X, in combination with the door D D, for the purpose described. 3. In a carpetsweeper, the handle attached to the ends of the sweeper, the fulcrum of said handle being above. the brush-roller, in combination with said brush-roller, and suitable slots or notches, substantially as described.
